    Hi Nadun. Welcome to the famous Physics Forums. :smile:

    I'm sure that Mr Google will be able to help with any and every detail you seek. But if there remain some unanswered questions, post them and we'll examine them.

    A crystal set doesn't need a battery, it is totally powered by the tiny microvolts of electricity picked up by your piece of wire aerial sitting in the electromagnetic field generated by a distant radio transmitting tower.

    Good luck with your crystal set experimentation!
